1. Viscosity and Buoyancy Physical Properties

2. Viscosity • A fluids resistance to flow • High Viscosity: the fluid is thick and flows slowly • Low Viscosity: the fluid is think and flows fast

3. If I poured each of these liquids out, which would have a high viscosity? How can I prove it?

4. Buoyancy • The ability to exert an upward force on an object immersed in it

5. Buoyancy • If the buoyant force is greater than or equal to the weight of the water displaced, then the object will float

6. Buoyancy Buoyant force is greater than or equal to weight = float Weight is greater than buoyant force = sink

7. Compressibility • A measure of how much the volume of matter decreases under pressure • Gases are easily compressible because of the space between the particles • Used in automobile airbags to absorb the energy of an impact
